Answer 1

Answer:

1. 7x+5y=19    

(+)-7x-2y=-16       step one

____________

$\frac{3y}{3\\}$=$\frac{3}{3}$                   step two

y=1

____________

since you have the value of y u can plug it in in either of the equations.

7x+5(1)=19        step three

____________

7x+5-5=19-5     step four

____________

$\frac{7x}{7}$=$\frac{14}{7}$

x=2                     step five

____________

You can check whether the answers are correct by plugging them back in.

7(2)+5(1)=19

14+5=19

19 equals 19 so it checks.

You can do the same thing for the rest.
